Overly soulful covers of rock songs done by pop singers are almost always annoying (see Joss Stone's "Fell in Love with a Boy"), but Kelly Clarkson has always seemed genuine enough that I'm willing to buy that this cover of "Seven Nation Army" comes from a place of fandom, and not an attempt to seem vaguely alternative. Also, it's kind of funny and a little cute when she jumps around in a circle.
